TDA8920C
2 à 110 W class-D power ampliï¬er
Rev. 01 â 29 September 2008
Preliminary data sheet
1. General description
The TDA8920C is a high-efï¬ciency class-D audio power ampliï¬er. The typical output
power is 2 à 110 W with a speaker load impedance of 4 â¦.
The TDA8920C is available in both HSOP24 and DBS23P power packages. The ampliï¬er
operates over a wide supply voltage range from ±12.5 V to ±32.5 V and has a low
quiescent current consumption.
2. Features
I Pin compatible with TDA8950/20B for both HSOP24 and DBS23P packages
I Symmetrical high operating supply voltage range from ±12.5 V to ±32.5 V
I Stereo full differential inputs, usable as stereo Single-Ended (SE) or mono Bridge-Tied
Load (BTL) ampliï¬er
I High output power at typical applications:
N SE 2 à 110 W, RL = 4 ⦠(VP = ±30 V)
N SE 2 à 125 W, RL = 4 ⦠(VP = ±32 V)
N SE 2 à 120 W, RL = 3 ⦠(VP = ±29 V)
N BTL 1 à 210 W, RL = 8 ⦠(VP = ±30 V)
I Low noise in BTL operation due to BD modulation
I Smooth pop noise-free start-up and switch off
I Zero dead time Pulse-Width Modulation (PWM) output switching
I Fixed frequency
I Internal or external clock switching frequency
I High efï¬ciency
I Low quiescent current
I Advanced protection strategy: voltage protection and output current limiting
I Thermal foldback
I Fixed gain of 30 dB in SE and 36 dB in BTL
I Full short-circuit proof across load
3. Applications
I DVD
I Mini and micro receiver
I Home Theater In A Box (HTIAB) system
I High power speaker system
